Since Plotly.js is known to use D3.js under-the-hood, for many, this JavaScript library has been a savior when it comes to creating D3.js graphs, rather than using the D3.js by itself.
D3.js
When it comes to the creation of beautiful charts, D3.js is the first name that comes to the mind. Known to be an open-source project, the charts in D3.js are rendered using the HTML, CSS, and SVG and brings with it many powerful features which were previously missing from many existing libraries.
Features like ‘Exit’ as well as ‘Enter’ as well as their familiarity with jQuery or Prototype, has made D3.js one of the best JavaScript libraries.
However, one thing which needs to be kept in mind is that D3.js doesn’t work well with older browsers, namely IE8.

ChartJS is one of the best JavaScript libraries with which you can create charts with beautiful flat designs. Made to be responsive by default, the charts created with ChartJS works well on both mobiles and tablets.

Chartist.js
Another JavaScript library with which you can create beautiful and responsive charts is ‘Chartist.js’. This JavaScript library was born as a result of the developer community getting frustrated with the highly priced JavaScript libraries.
The best part about this JavaScript library is that it is rendered using SVG and as such, it can further be customized through CSS3 media queries and Sass.
One thing, that needs to be kept in mind is that Chartist.js provides animations, though they will only work in modern browsers.
Ember Charts

Conclusion
Like with any other numerous options, there are no set criteria on which JavaScript charting library you should go for. It all depends on your needs. If, you as a developer, want to have control over all of your charts, then, you should definitely opt for D3.js.
